Updating MAC Access-Lists on Cisco Catalyst Switches

I am looking at what would be the right way to edit an existing MAC ACL by adding entries above or below a particular entry. If I edit a MAC-ACL (unlike IP ACL which uses sequence number to sort rules) - it always puts the newly added rule to the end of the list.

Second question is if I delete an existing MAC-ACL that's already applied on some L2 ports, and recreate it with the same name, what would be the behavior ? Does it destroy all the TCAM entries after ACL delete or would it still keep them because some interfaces are referring to it ??
